Referring now to all the figures of these drawings, l indicates the sill of a window frame and 2, 2 the side rails thereof having sash-members 3 and inner and outer sash grooves 4, 4'.

In the preferred embodiment of my invention illustrated in Figs. 1 to 6 and 7 to 1'7, I provide on my ventilator 5 adjacent to the opposite ends thereof and projecting from the edge thereof,

posts or pivot members 6 which are readily removable from and preferably have a slidable connection with means on the window sill at the corners adjacent to the inner sash grooves 4 and closely adjacent to the side frame members 2, 2',

and I also preferably provide similar members 6 engageable with means at the center of the window sill. These pivot or post members 6 are preferably slidably and rotatably mounted in vertically disposed sockets 1 formed in the window sill. In Fig. 1, three of these sockets 'l are shown, two of them being disposed adjacent to the sash grooves 4 of the inner sash 3 and the other being disposed at the center of the sill on the moulding adjacent to the plane of the sash rail. The sockets 'l comprise Vertical holes or bores made in the material of the sill or molding and preferably lined with metal tubes which are inserted therein so as to provide metal walled sockets or pivot bearings 1 for the pivot members or posts 6.

In Figs 1 to 'la and 11, these posts have connected thereto grooved holders 8 for ventilator body element 9 which is provided with louvres I0 of conventional construction. In Figs. '7 and 7a the body element 9 is fastened to grooved holder members 8 and swings on the post members which form hinged pins for sections 9', Ela of the louvred body element 9. In this construction, the meeting ends 9b, 9c of sections of the body element 9 are adapted to swing inwardly into the room about the corner posts or pivots to enable access to the window without removal of the ventilator, and in closed position said ends engage a catch I0' on the window sill. The meeting ends may, if desired, be swung outwardly of the window frame to function as air deectors.

In Fig. 11 I have combined with corner posts 6 and corner holders 8, such as hereinabove described in relation to Figs. 1 to 7a, a central post 6 to which sections 9d, 9e of a louvred body element 9 are hinged. In this construction, the outer ends of the louvred body element may be swung inwardly on the central hinge pin to permit temporary access to the window sash or frame without removal of the ventilator, or if desired, under suitable weather conditions may be swung outwardly to function as air deflectors for dellecting air from outside into the room.

In Figs. 12 to 16, I have shown a construction comprising two pairs of posts 6 each pair projecting from the bottom edge of a holder frame l l composed of end members l2, I2 and a bottom member I3 connected together to produce a grinding frame or pocket for a series of louvreforming round bars I3 having central portions I3 reduced in diameter and end portions i3a of increased dimensions so that when mounted in said frame, said bars will form between such 75 members Ventilating slots or louvres 13b,

In Fig. l5 I have illustrated straight strips I4 instead of round bars. In said Fig. 15 the ends HIa are similarly of increased dimensions to provide slots I4 between the mounted strips.

In Fig. 16, I have shown similar strips l5 which are arranged obliquely to the end blocks I5' so as to enable upward deflection of the air by the outer surfaces IF:a as well as providing Ventilating slots or louvres 15b between the strips.

In Fig. 1'7, I have shown a construction in which the sections of the body element of the ventilator are made of metal and connected to post members (ic and holders 8 in a manner similar to that shown in Figs. '1 -'7a. In this construction, however, one end of each of the post members 6C is provided with a screw thread 6d and is screwed into the upper rail of a window frame instead of into the sill. These sections' of the body element in this construction are also locked to the holder members by pins I6 so as to prevent dropping of the same by gravity. In other respects the construction is similar to that shown in Figs. '7 and 7a.

Having described my invention, I claim:

1. A ventilator for windows, comprising a pair of ventilator body elements, holders for engaging the edges of each member of said pair of body elements, located at the corners of the horizontal member of a window frame and at the middle thereof, at least one of said edge holders being provided with a vertical post having a releasable sliding connection with said horizontal member of the window frame.

2. A ventilator for windows, comprising a ventilator body element having Ventilating louvres, an edge-holder in which said body element is removably mounted, and vertical post members and bearings therefor for removably mounting said edge-holder member, said post members and bearings being connected with a horizontal member of the window frame at the corners of the window frame adjacent to the inner sash groove.

3. A ventilator for windows, comprising a ventilator body element having Ventilating louvres, an edge holder in which said body element is removably mounted, vertically disposed bearings connected with the window sill adjacent to the inner sash groove at the corners between hori- Zontal and vertical members of the window frame and vertical post members slidable in said bearings for mounting said edge-holders.
